The Innovative Design of Low Cost Embedded Controller for Complex Control Systems

With the availability of ever more powerful and cheaper products, the number of embedded devices deployed in the real world has been far greater than that of the various generalpurpose computers such as desktop PCs. An embedded system is an application-specific computer system that is physically encapsulated by the device it controls. It is generally a part of a larger system and is hidden from end users. There are a few different architectures for embedded processors, such as ARM, PowerPC, x86, MIPS, etc. Some embedded systems have no operating system, while many more run real-time operating systems and complex multithreaded programs. Nowadays embedded systems are used in numerous application areas, for example, aerospace, instrument, industrial control, transportation, military, consumer electronics, and sensor networks. In particular, embedded controllers that implement control functions of various physical processes have become unprecedentedly popular in computer-controlled systems (Wittenmark et al., 2002 ; Xia, F. & Sun, Y.X., 2008). The use of embedded processors has the potential of reducing the size and cost, increasing the reliability, and improving the performance of control systems.
